Mercury's atmosphere contains small amounts of hydrogen, helium, and oxygen gasses. It also has even tinier amounts of sodium, potassium, calcium, and magnesium. Some of the gas particles come from the solar wind. Others are made by radioactive decay or when micrometeorites smash into the surface.

Mercury is made out of a large percentage of heavier elements, mainly iron. It is essentially a large metal ball of iron with a very thin silicate crust. Mercury's core makes up about 75% of the planet. Its thin mantle, or crust, is only about 300 to 400 miles thick (500 to 600 km).

Mercury, shown at left in a Mariner 10 image, is the closest planet to the Sun - it orbits at an average distance of 57,910,000 km, or 0.38 AU from Sun. (An AU is an Astronomical Unit; it is equal to the distance between the Sun and the Earth.) Mercury's diameter is 4,880 km and it has a mass of 3.3023 kg. Mercury has been known since at least the time of the Sumerians (3rd millennium BC). Although the Greeks had two names for it, Apollo for its apparition as a morning star and Hermes as an evening star, they knew that the two names referred to the same object. We know this planet as Mercury - the name of the Roman counterpart to Hermes.

Mercury is the closest planet to the Sun. Its orbit around the Sun is very elliptical, like a stretched out circle, compared to those of the other planets. Mercury's distance from the Sun ranges from 28.6 million miles (46 million km) to 43.4 million miles (69.8 million km)

Well, not mercury. As far as we can tell it is made of rock like our Earth, but with a high metals content, about 70%.
